We have an update to our recent episode, Skeptic Check: Drone Panic. If you remember, our guest astronomer Andrew Franknoi recalled the story of Jimmy Carter having seen something mysterious in the sky when he was governor of Georgia in 1969. Astronomers at the time suggested it was likely Venus, as has been the case with other sightings, and for decades that was a widely accepted understanding of what he saw. But there is more to the story, as was brought to our attention by multiple BPS listeners. So, we invited Andrew back to discuss the revised account, and its more satisfying scientific resolution.Guest:Andrew Fraknoi - Professor of Astronomy at the Fromm Institute of the University of SanFrancisco Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

When several mysterious objects were spotted flying over New Jersey, their unknown identity led to frightening rumors, and triggered frustration and alarm among some residents of the Garden State. What were these objects, and if they were drones, as some appeared to be, were they friendly or foe? Many of the objects have now been identified. We talk about what happened when calmer heads prevailed and consider what the Great Drone Panic might havein common with other episodes involving objects cruising the skies. Also, why one expert thinks the event gave birth to a new UFO subculture. Guests:Andrew Fraknoi - Professor of Astronomy at the Fromm Institute of the University of San Francisco Mick West - Investigator of conspiracy theories and UFO sightingsGreg Eghigian - Professor of history and bioethics at Penn State and author of “After the Flying Saucers Came: A Global History of the UFO Phenomenon”Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

After helping to sequence the human genome more than twenty years ago, biochemist Craig Venter seemed to recede from the public eye. But he hadn’t retired. He had gone to sea and taken his revolutionary sequencing tools with him. We chatted with him about his multi-year voyage aboard the research vessel Sorcerer II, its parallels to Darwin’s voyage, and the surprising discoveries his team made about the sheer number and diversity of marine microbes and their roles in ocean ecosystems.Guests:Craig Venter - Genomicist, biochemist, founder of the J. Craig Venter Institute, and co-author of “The Voyage of Sorcerer II: The Expedition that Unlocked the Secrets of the Ocean’s Microbiome.”Jeff Hoffman - Lab manager at the J.

Our information age is increasingly the disinformation age. The spread of lies and conspiracy theories has created competing experiences of reality. Facts are often useless for changing minds or even making compelling arguments. In this episode, author Naomi Klein and science philosopher Lee McIntyre discuss why the goal – not simply the byproduct - of spreading disinformation is to polarize society. They also offer ideas about how we might find our way back to a shared objective truth.  Guests:Naomi Klein - Associate professor of Geography at the University of British Columbia and a co-director at the Center for Climate Justice. Author of Doppelganger: A Trip Into the Mirror WorldLee McIntyre - Philosopher of science and a research fellow at the Center for Philosophy and the History of Science at Boston University, and author of Post-Truth and On Disinformation.Featuring music by Dewey Dellay and Jun MiyakeOriginally aired December 11, 2023 Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

“To live is to count and to count is to calculate.” But before we plugged in the computer to express this ethos, we pulled out the pocket calculator. It became a monarch of mathematics that sparked a computing revolution. But it’s not the only deceptively modest innovation that changed how we work and live. Find out how sewing a scrap of fabric into clothing helped define private life and how adding lines to paper helped build an Empire. Plus, does every invention entail irrevocable cultural loss?Guests:Keith Houston – author of “Empire of the Sum: The Rise and Reign of the Pocket Calculator.”Hannah Carlson – teaches dress history and material culture at the Rhode Island School of Design, author of “Pockets: An Intimate History of How We Keep Things Close.”Dominic Riley – bookbinder in the U.K.Featuring music by Dewey Dellay and Jun Miyake*Originally aired October 30, 2023Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

The SETI Institute’s search for alien biosignatures and technosignatures depends on radio telescopes. You may have seen the stunning photos of massive telescope arrays in the desert, but what types of alien signals might help researchers actually detect with those giant dishes?In this fourth episode, Brian Edwards talks with physicist Chenoa Tremblay, a COSMIC Project Scientist who is based at the Very Large Array in New Mexico. They dig into the important role radio telescopes play in SETI, how powerful computers have supercharged the search for life off Earth, and imagine what kinds of biosignatures and technosignatures of alien life we are most likely to find.Music by Jun MiyakeYou can support the work of Big Picture Science by joining us on Patreon.

This year has been a spectacular one for celestial phenomena. The northern lights delighted in unexpected ways while a total solar eclipse cast a shadow across North America. Those events were enough to make it a memorable year, but 2024 also shook up our understanding of the universe. A new reading of Voyager 2 data may explain Uranus’s weird magnetic field. And the impressive James Webb Space Telescope has detected an early and incredibly distant galaxy. Join us in our look back at some of the top space news from 2024.Guests:Andrew Fraknoi – Professor of Astronomy at the Fromm Institute at the University of San Francisco and SETI board member Jamie Jasinski - space plasma physicist for the NASA Jet Propulsion Laboratory, and author of a recent paper re-examining data from the Voyager 2 mission, published in Nature.Phil Plait - astronomer, author, science communicator and frequent contributor at Scientific American.Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

Just because something is invisible doesn’t mean it isn’t there. We can’t see gases in our atmosphere, such as carbon dioxide, oxygen, and nitrogen, but we benefit from their presence with every breath we take. From the bubbles that effervesce in soda to the vapors that turn engines, gases are part of our lives. They fill our lungs, give birth to stars, and… well, how would we spot a good diner without glowing neon? In this episode, a materials scientist shares the history of some gaseous substances that we don’t usually see, but that make up our world.Guest:Mark Miodownik – Professor of materials and society at the University College London and the author of “It’s a Gas: The Sublime and Elusive Elements That Expand Our World.”Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.
